]FileInfo class
Represents a path to a file and a file referred to by this path and provides methods for manipulating it. Objects of this class should only be allocated using System::MakeObject() function. Never create instance of this type on stack or using operator new, as it will result in runtime errors and/or assertion faults. Always wrap this class into System::SmartPtr pointer and use this pointer to pass it to functions as argument.
class FileInfo : public System::IO::FileSystemInfo
